Temp reading goes up instead of down when my 1 year old Haier window AC is turned on

SOURCE: window ac unit is not blowing cold air

When the unit is running, go outside and put your hand near the condenser fins, this air that comes out should be slightly warmer than the ambient temp. If it is not you will need to take the unit out of the window and out of its outer case and clean the condenser fins from the inside, this is no easy task as it is very hard to reach. You will want to get a small (toothbrushed sized) brass bristled brush with a long handle. Make sure the evaporator coil (in the front) recieves the same attention and wash the mesh filter that goes in front of the evaporator. Re- assemble and enjoy the cold air.

open the service panel to check for control voltage of 24volts when tstat calling, The contactor should be pulled in, if contactor is down,and contacts appear to be clean, and the unit is still not running, it is a bad compressor. to test this unplug the black wire from the compressoror at contactor,w/ power off! Turn on power if fan works normally it's a bad compressor. However if you see a swollen split cap(5 wires to a soup can looking w/ the terminal C,F,and Comp), switch it first and start at square one.
You also need to consider the high pressure switch if its cycling on off on off.

DOES THE HOUSE FEEL DRIER IF IT IS 80 OUTSIDE WITH ALOT OF HUMIDITY THE UNIT WILL RUN FOR A LONG TIME TO REMOVE THE MOISTURE(HUMIDITY) OUT OF THE HOUSE BEFORE TEMP DROPS DRAMATICALLY IS THERE WATER COMING OUT OF THE DRAIN PIPE OUTSIDE

SOURCE: haier window airconditioner cooling is not effective

there is a temperature sensor bulb in front of the evaporator. check if it is too near to the coil. move iit away about an inch.

SOURCE: Air conditioner constantly running, not cooling house

Ours was worse than yours. It was not frozen up, but it did need freon. The tech told us that the compressor coil (the unit in the attic) was leaking freon and that the unit would have to be replaced within a year, but adding freon dropped the temperature inside from the mid-80s to the mid-70s (on 100 degree days). It might go lower, but we don't set the thermostats below 76. We paid $80 for the service call plus another $197 for 3 lbs of freon (for our 4-ton unit). Total cost: $274. The quote to replace the system with a new 14 SEER unit is $7,000 -- but this will get us through the summer. Oh, be sure to replace your filters monthly and keep your condensor fins clean. Spray them down with a hose (even while the unit is running), make sure there are no leaves or other trash blocking them, and make sure you have 2 feet of clearance around the condensor. Putting plants or other objects right up against it will impede its operation. Good luck!
